BATH-TUB.

Specification of Letters Patent.

Patented Sept. 12, 1916.

Application filed December 1, 1915. Serial No. 64,571.

T 0 all whom it may concern:

Be. it known that I, WILLIAM T. WIL- LIAMS, a subject of the King of Great Brit ain, residing at Medicine Hat, in the Province of Alberta and Dominion of Canada,

have invented new and useful Improvements in Bath-Tubs, of which the following is a specification.

. This invention relates to bath tubs and particularly to the type of bath tub provided with a rim so constructed as to provide a continuous water way encircling the tub.

The, primary object of the invention is to provide the tub with a supplemental rim, which when attached to the rim of the tub provides a continuous water passage having a water supply pipe therein and gradually tapering toward its opened lower edge so that, the discharge of water from the supply pipe into the water passage will be noiseless.

A further object of the invention is to provide the tub rim with a continuous offset and a flange spaced therefrom so that when the supplemental rim which cooperates with the tub rim to provide the continuous water passage about the tub is connected with the flange on the tub rim the inner lower edge of the supplemental rim will lie in spaced relation to said offset and in a plane flush with the sides of the tub.

A still further object of the invention is to arrange the water supply pipe within the continuous water passage surrounding the tub in such a manner that the water discharged from the supply pipe will be directed into the tub to clean any scum which might adhere to thesides or bottom of the tub therefrom and also to regulate the temperature of the water contained in the tub for bathing purposes.

With these and other objects in view the invention resides in the novel combination and arrangement of parts which will be hereinafter described and more particularly pointed out in the claims.

The preferred embodimentof the invention has been illustrated in the accompanying drawing, although no restriction is necessarily made to the precise details of construction therein shown, as changes, alterations and modifications within the scope of the claims may be resorted to when so desired. Like characters of reference denote corresponding parts throughout the several views in the drawing in which Figure 1 is a top plan view of a. bath tub constructed in accordance with the inven-- tion part of the supplemental rim being broken away to more clearly disclose the invention. Fig. 2 is a cross section on the line 2-2 of Fig. 1. Fig. 3 is a vertical longitudinal sectional view on the line 3-3 of Fig. 2. Fig. 4 is a detail sectional view on an enlarged scale through a portion of the tub to clearly disclose the shape of the tub rim and the supplemental rim connected there with which provides the continuous water .way about the tub body. Fig. 5 is a view similar to Fig. 4 showing a modified form of supplemental rim.

Referring now to the drawings in detail the numeral 1 designates a bath tub which has been constructed to embody the broadprinciple of the invention for the sake of illustration, it however being understood that the broad principle of the invention is not limited to bath tubs but may be used advantageously upon stationary wash basins and the like when desired.

The tub 1 has its upper edge curved upwardly and outwardly to provide a rim 2, said rim being provided upon its inner face at the intersection thereof with the sides of the tub with a continuous ofiset 3 and at its outer edge with a vertically extending flange 4.

The upwardly and outwardly curved portion of the rim 2 between the flange 4 and offset 3 has a curvature which gradually diminishes toward the foot of the tub for a purpose which will be hereinafter described. I

Cooperating with the upwardly and outwardly curved portion of the rim 2 is a supplemental rim 5, said rim being curved and provided with a continuous thickened portion 6 having a groove 7 therein of greater width than the flange 4, to receive the same when the supplemental rim 5 is positioned upon the tub body.

When the flange 4 of the rim 2 is ositioned in the groove 7 the supplemental rim 5 is supported by said flange in such a manner as to provide a continuous water way 8 above the upwardly and outwardly curved portion of the rim 2 and gradually decreasing in width toward the oflset 3 above which the lower inner edge of the supplemental rim 5 is held in spaced relation by the flange 4 so that a continuous outlet 9 is provided in the water way 8.

It will of course be understood that to effect a water tight joint between the flange 4 and side walls of the groove 7 it will be necessary to fill the space'therebetween with a rubber packing or a cementitious material which would answer this purpose and also enable the supplemental rim 5 to be removed from the rim 2 when found necessary.

A water supply pipe 10 extends entirely around the tub within the water way 8 and is connected at the side of the tub with a faucet 11 which is connected with the usual hot and cold water supply pipes not shown in the drawing.

The water supply pipe 10 is provided at intervals along its length with cushioning members 12 between which are arranged in spaced relation elongated outlet ports .13 adapted to discharge the water from the supply pipe 10 upon the upwardly and outwardly curved surface of the rim 2 so that 'the splashing of the water within the water way 8 is prevented, while the cushioning rings 12 prevent the rattling of the pipe 10 against the rim when a water hammer forms in the pipe.

An overflow pipe 13 is provided which has one end thereof extending through an opening in the upwardly and outwardly curved portion of the rim 2 at the side of the tub and into the water way 8 to a point in alinement with the bottom of the water supply pipe 10 so that when the water level in the tub reaches the bottom of the water supply pipe 10 it may be discharged through the pipe 13.

When it is desired to fill the tub with water the flow of water through the supply pipe 10 is regulated by the faucet 11 said water being discharged through the openings in the supply pipe 10 against the upwardly and outwardly curved inner edge of the rim 2.

Through the limited space between the offset 3 and the inner edge of the supplemental rim 5 the water in the water way 8 is directed by the upwardly and outwardly curved surface of the rim 2 and the curved inner face of the rim 5 through the opening 9 and down the sides of the tub in a noise less manner and in such a manner as to regulate the temperature of the water within the tub. I

It of course being understood that the admission of hot or cold water into the wa.-' ter supply pipe 10 and the quantity discharged therefrom is controlled by the fau- -cet 11. By providing the rim with an upwardly and outwardly curved surface which gradually increases in curvature toward the ends of the tub the water in the water way is given greater impetus at the ends of the tub thus facilitating the regulating of the temperature of the water in the tub and the cleaning of the same after a bath has been taken therein.

The supplemental rim shown in Fig. 5 in the drawing is identical in construction with that shown in the preferred form' of the invention with the exception that the lower inner edge of the rim is provided with a head 14 and a portion of the rim adjacent said bead bent inwardly to cause the bead to be positioned in closer relation with the upwardly and outwardly curved rim 2, thus adding to the attractive appearance of the supplemental rim. 85

From the foregoing statements taken in connection -with the accompanying drawing it is at once apparent that a bath tub of the type described has been provided which is simple in construction, inexpensive of manufacture and highly eflicient in use.

Having thus described the invention what is claimed as new is:

1. A bath tub havingits upper edge extended outwardly and provided with a flange, a grooved rim supported by said flange and overlying the extended upper edge in spaced relation to provide a continuous water way gradually tapering toward the bottom thereof, a water supply 100 pipe disposed in the water way, and a fau- -cet connected with said pipe.

2. A bath tub having its upper edge curved upwardly and outwardly, said up wardly and outwardly curved upper edge having a continuous ofi'set in its inner face at its point of intersection with the tub body, a curved rim adapted to overlie the curved upper edge to provide a continuous water way, a thickened portion 011 the rim provided with a continuous groove, a flange extending vertically above the curved upper edge and disposed in said groove to hold the lower inner edge of the rim in spacedrelation with said offset, a water supply pipe disposed in the water way, and a faucet connected with said pipe.

3. ;A bath tub having an outwardly and upwardly curved rim provided with a continuous ofi'set at the intersection of the rim 1 with the tub body, a flange extending vertically above said'rim in spaced relation to;said offset, a supplemental rinr having a continuous thickened portion provided with a groove to receive said flange, said supplemental rim being curved to enable the greater portion thereof to overlie the rim of the tub in spaced relation with the inner lower edge of the supplemental rim lying in a plane flush with the sides of the tub,

a supply pipe interposed between said rim and provided with cushioning rings, said pipe having spaced openings between said rings adapted to direct the water from the pipe against the upwardly and outwardly curved rim, and a faucet connected with said pipe.

In testimony whereof I afiix my signature Witnesses:
